A method for dynamic notification management at a head mounted display (HMD) includes presenting, at the HMD, an augmented reality display, receiving, at a processor controlling the HMD, a notification from an application for display at the HMD, receiving, at the processor at a first time, first sensor data from one or more of a camera or a microphone, determining, based on the first sensor data, a first value of one or more factors associated with a probability that a user of the HMD is currently in a real-world conversation, determining an importance value of the received notification at the first time, and determining whether to display the notification from the application based on a comparison of the first value of the one or more factors associated relative to the importance value of the received notification.

Provided is a head-up display including a liquid-crystal panel including a display screen provided at a front surface thereof, a Fresnel lens opposite the liquid-crystal panel from the display screen, a light-diffusion structure between the liquid-crystal panel and the Fresnel lens, a backlight that emits light toward the Fresnel lens, a body part accommodating the Fresnel lens, and a mirror that forms a virtual image corresponding to an image displayed on the display screen of the liquid-crystal panel, in a target space. The body part has a step-shaped structure including a first step surface and a second step surface, the first step surface and the second step surface are oriented in the same direction as the front surface of the liquid-crystal panel, the first step surface is located on the liquid-crystal panel side from the second step surface, and the liquid-crystal panel is supported on the second step surface.

A method which makes it possible to immerse a user in a virtual reality application is described. The method includes controlling the movement of an avatar of a user in a synthetic scene and controlling the movements of a video acquisition system depending on the detected movements of the head of the user. The method also includes playing back content on a screen of a virtual reality helmet of the user, the content being a video stream acquired by the video acquisition system if the position of the eyes of the avatar is in a synthetic object whose volume can be included in a volume in which the video acquisition system is likely to move.

A system may comprise a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye.

There is provided a display device for a vehicle, the display device including: a display unit that is visible to an occupant of a vehicle; a memory; and a processor that is connected to the memory, the processor changing a content image displayed on the display unit so as to be displayed in the same direction as a direction in which a travel path of the vehicle curves.

The present disclosure provides a virtual reality system. The virtual reality system of the disclosure, comprising: a head-mounted display, an input device and a positioning module, wherein the head-mounted display comprises a central processing unit, a camera module connected with the central processing unit and a wireless connection module; the camera module comprises a binocular fisheye camera, an IR camera and a TOF camera, the positioning module comprises a first inertial measurement unit and an electromagnetic receiver provided on the head-mounted display, a second inertial measurement unit and an electromagnetic transmitter provided on the input device; the central processing unit, configured to implement data interaction and command control with the binocular fisheye camera, the IR camera, the TOF camera, the wireless connection module, the first inertial measurement unit and the electromagnetic receiver.

An example device comprises: a head-mounted display; a housing for the head-mounted display, the housing including an external surface; sensors to monitor a wearer of the head-mounted display; a visual indicator at the external surface; and a controller. The controller is generally to: control subsets of the sensors to be on or off based on respective permissions for usage of subsets of the sensors; and control the visual indicator to indicate respective status of the subsets of the sensors.

A method and apparatus to assist people with hearing loss. An augmented reality device with microphones and a display captures speech of a person talking to the wearer of the device and displays real-time captions in the wearer's field of view, while optionally not captioning the wearer's own speech. The microphone system in this apparatus inverts the use of microphones in augmented reality devices by analyzing and processing environmental sounds while ignoring the wearer's own voice.

The present invention relates to a method for improving the image quality of a HUD system, the HUD system comprising an image display device (1) and a reflecting element (3) having a partially transmissive first reflective surface (3a) and at least one partially transmissive second reflective surface (3b) substantially parallel thereto, and a polarization-dependent reflection layer (13) and/or an anti-reflection layer (14) and/or an optical birefringent layer (15), wherein the second reflective surface (3b) is arranged on the side of the first reflective surface (3a) opposite the image display device (1) and wherein the reflecting element (3) is adapted to produce reflected light beams (12a, 12b) from incident light beams (11) which are originating from the points of the image generated by the image display device (1) and arriving at the reflective surfaces (3a, 3b) and to reflect a portion of the reflected light beams (12a, 12b) toward a design detection point (23a), characterized by —determining for each of the incident light beams (11) reflected by the reflecting element (3) in the direction of the design detection point (23a) an optimal polarization state to which the intensity ratio of the reflected light beams (12a, 12b) reflected by the first reflective surface (3a) and first reflected by the second reflective surface (3b) during the reflection of the given incident light beam (11) is minimal, and —setting the polarization states of the incident light beams (11) reflected by the reflecting element (3) in the direction of the design detection point (23a) by means of a polarizing element (20) arranged in the path of the incident light beams (11) in accordance with the previously determined optimal polarization states. The invention also relates to a polarizing element and a HUD system.

A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.
